Verse 31
Except these abide in the ship, ye cannot be saved - God, who has promised to save your lives, promises this on the condition that ye make use of every means he has put in your power to help yourselves. While, therefore, ye are using these means, expect the co-operation of God. If these sailors, who only understand how to work the ship, leave it, ye cannot escape. Therefore prevent their present design. On the economy of Divine Providence, see the notes on Act 23:35.
